Roduct Designer (Mobile) - B2B SaaS | London (Hybrid) | Up to £75k I'm working with a fast-growing SaaS company looking for their first dedicated mobile Product Designer. This is not a typical design role. You'll be building mobile tools used on construction sites-by people working outdoors, on shared devices, often with poor connectivity. Think: ?? Task updates ?? Photo logging ?? Daily reporting ?? Voice capture If you've designed for clean, ideal conditions-this will feel very different. ?? The role Own mobile design end-to-end (iOS & Android - Flutter) Design complex workflows, not just screens Work closely with engineers to get details right in production Design for real-world constraints (offline, speed, usability under pressure) Help raise the bar from 'we have an app' ? 'this is genuinely great to use' ? What they're looking for 4 years in product design Strong mobile experience Experience with complex, multi-step workflows Comfortable working closely with engineers Someone who takes ownership and pushes for quality Bonus: B2B / SaaS Field / operational tools Flutter / cross-platform experience ?? Probably not for you if: You focus mainly on visual polish over usability You prefer handing off designs rather than owning outcomes You haven't worked on complex product problems Why this role is interesting First mobile-focused designer in the team High ownership real product impact Mobile is a key growth area for 2026 Small, senior team ?? London (Moorgate - 2 days/week) remote ?? Global team (UK / Europe / APAC) *Rates depend on experience and client requirements
